PUMP HANDLE.

Application filed May 18,

To all whom it may concern:

Be it known that I, Benson FRANK Form, a citizen of the United States,residing near Marion, in the county of Linn and State of Iowa, haveinvented certain new and useful Improvements in Pump'Handies; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will, enable others skilled in the art towhich it appertains to make and use the same.

This invention relates to pumps, and more particularly such as areoperated by wind power, as well as by hand, and the object of theinvention is to make it possible to easily and quickly connect, ordisconnect the handle with the pump-rod, even While said rod is moving.

The invention is fully disclosed in the description and claimsfollowing, reference being had to the accompanying drawing, in whichFig. 1 is a side elevation of my improved pump-handle as applied to apump of a familiar type. Fig. 2 is an elevation of the handle as seenfrom the pump-ward side, and showing a fragment of the pump-rod inposition. Fig. 3 is a fragmentary side'elevation, showing the handle inposition for engagement with the pump-rod. side sectional view, showingdetails of the latch.

In the drawing, the numeral 5 denotes the upper end of a pump cylinderor casing, to which is attached a fulcrum casting (3 provided with anupstanding guide 7 for the pump-rod 8. These may be of the usualcorstruction, except that the pin 9 which engages the puinp-handle ispermanently secured in the pump-rod, and projects each side thereof, asshown in Fig. 2.

To the fulcrum is pivoted a link 10, connecting with the handle 11in theusual way. The handle has a forked head to straddle the pump-rod. butthe upper portion of this head 12 is cut away central to the hole 13which engages the pump-rod pin. At 14; is pivoted a forked lever 15whose jaws are provided with half-holes'at 15, and are laterally flushwith the head, so as to play freely in the rod-guide. When in operativeposition, as shown in Fig. 1, the permanent stud of the pump-rod is heldbetween the jaws and the head, and serves the same purpose as theordinary pin or bolt in the hole of an undivided head. The long arm ofthe Specification of Letters Patent.

forked lever takes a-somewhat shorter curve than the handle, and at 15unites to form a single tail-piece 15, standing out somewhat from theunder side of the handle. To the handle opposite this end-piece ispivoted a latch-lever 16, preferably forked to straddle the handle aswell as the engaging end of the tail-piece. A spring 17 holds the latchin engaging position, and a stop 18 limits its movement under springpressure. The latch is disengaged by a grasp of the hand, and may beengaged by a similar grasp applied to the lever near the tail end. thecurved end of the tail-piece at 15 and the curved shoulder 16 of thelatch-lever permitting the parts to snap together in a manner that willbe readily understood. In practice the engagement is made in the mannerindicated in Figs. 1 and 3. With the jaws open, as shown in Fig. 3, theoperator catches the pump rod stud between them, and pushes the handleinwardly to the extreme position shown in Fig. 1. The curve of the mainlever then abuts against the fulcrum, and is forced to the latchingposition. This as well as the disengagement of the handle may be easilyeflected while the pump-rod is in motion, and is the Work of but amoment. This dispenses with the necessity of stopping the pump-rod toinsert a pin, or making a difiicult connection, by means of a pin withthe rod in motion, under conditions when such an operation is possible.

It is to be noted that a little wedging inclination is given to thelatch shoulder at 16". so that the constant pressure of the spring tendsto hold the main lever more tightly under the vibration to which it maybe subjected.

Having thus described my invention, I claim:

1. A pump-handle having a head divided across the pivot-hole, asimilarly formed jaw pivoted to the handle, and a latch-lever to holdthe jaw in operative position.

2. A pump-handle having a head divided across its pump-rod pivot hole, alever pivoted to the handle, and having a similarly formed pivot-jaw,and a latch-lever connecting with the handle and adapted to engage thefree end of the jaw lever.

3. A pump handle having a head divided across its pump-rod pivot-hole. alever with similarly formed jaws pivoted to the handle, and having itslonger arm curved in- Wardly of the handle so as to abut on someprojecting part of the pump, and a latch adapted to snap into engagementwith said long arm when it is forced against such :projection.

ehA pump-handle having a head divided acrbss'its"punip-rod pivot-hole, alever With similarly formed jaws, pivoted tothe'handl'e, a latch toengage the other end of the lever, 10 and a spring to force it into suchengagement, the engaging faces being slightly indined, wherebythe-spring tends to continuously tighten the engagement.
